The volume of a colloidal particle, V_C as compared to the volume of a solute particle in a true solution V_S, could be

Accepted Answer

Particle size of colloidal particle

= 1 m μ

to

100 m μ

(suppose

10 m μ

)

V_{C} = \frac{4}{3} π r^{3} = \frac{4}{3} π {(10)}^{3}

Particle size of true solution particle

= 1 m μ

V s = \frac{4}{3} π {(1)}^{3}

hence now

\frac{V c}{V s} = 10^{3}
